Re: 3/4" Scale J1e

Hello NP317, Great work with your Heisler! There is on more severe advantage using stainless steel for the jacketing: Thermal losses by radiation will be reduced a great deal due to the reflecting inner side of the jacket :idea: Experience with both my locos which are equipped with boilers and jacke...

Re: A Real Dirty Job

Hello friends, Watching the atempt to refurbish an old and worn piece of locomotive with interest. I did a similar job during the last months. The only difference is, this locomotiive is well known to me for I built it myself some 30 years ago :lol: For I didn't like the painting process :oops: (and...

Re: steam locomotive emulator

Hello gregoryc, What do you think about the good old Train Simulator? Maybe this will be only working with ancient WIN 2000 or Expert on your labtop yet? Years ago I checked out, if the calculations used with this programme were true regarding the real thing. Found out that both drawbar power and -f...

Re: Steam Turbine Question

Hello Phil, RET, Just let me add some photos to show how a simple construction will do, too. Using a standard gear wheel (made of aluminium, if you can get) will work just fine :idea: . The steam is directed tangential along the wheel and is exausted after about 90°towards the generous exaust. Force...

Re: Steam Turbine Question

Hello Phil, Maybe the air inlet should be much smaller in diameter for using steam. A diameter of about 1 mm (1/32") should be fine! In addition the outlet might be enlarged to reduce back preasure. For use with steam the simple ball bearing to be seen won't work for a long time, anyway. Working ste...

Re: My N&W class A 1239 (gauge 5", 1 in 10 scale)

Hello friends, We had a great weekend at Dresden :D . For the curves of the layout were a little tight for my A, I had it steaming on a roller board. Much better for the interested visitors to see her life directly in front of their eyes 8) instead down on the floor (so I think). We had her working ...

Re: Power Reverser questions

Hello Moron, Thank you for your precise information! For power reversers were not common in Europe, any information would help for better understanding that system. I used Steam Cyclopedia as basis for my model construction. And yes, the precise, small and low loss valve is the heart of the reverser...

Re: Power Reverser questions

Hello Tim, In case your reverser will work on steam reliable (piston rings, stuffing box and reverse valve), this maybe o.k. Of course, speed is increased a great deal in regard to work on water! Maybe it's getting instable or creaping, cause there is almost no damping in this simple proportional st...

Re: 3/4" Scale J1e

Harold, We (hobby) modelers can hardly match with such precision industrial products made by very scilled mechanics! :oops: The way I found (and which I recommend to other modellers) was to make simple tools :idea: before starting production! Means a little patience ... And to use a turntable whenev...

Re: Disney American

But your work is Impressive as always! :!: Just wanted to note that the check valves you made were of the same construction as mine. They worked reliable for years with...
